Alas I do not know, I am just watching what Dries does because he does it right. Despite just a year ago he was not too convinced that the Schema API is a good idea, yesterday he committed just that. We had raw SQL statements with Drupal 5.0 and below, in 5.0 we began to use the thin Drupal database layer to write SQL install statements and now we can just use arrays to achieve the same. No longer can "not sure whether this works with postgresql" hold up a patch. Yay.
On an another note, I wanted to remove the locks from Drupal -- and equally yesterday it happened because David Strauss brought in a better patch. Thanks!
